For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life. – John 3:16

Christians have to trust the Spirit after conversion, but the sinner’s business, if he would be saved, is not with trusting the Spirit nor with looking to the Spirit, but looking to Christ Jesus, and to Him alone…When thou hast thus believed, believe in Him as man. Believe the wondrous story of his incarnation; rely upon the testimony of the evangelists, who declare that the Infinite was robed in the infant, that the Eternal was concealed within the mortal; that He who was King of heaven became a servant of servants and the Son of man…Then, specially, if thou wouldst be saved, let thy faith behold Christ in His perfect righteousness. See Him keeping the law without blemish, obeying His Father without error; preserving His integrity without flaw. All this thou are to consider as being done on thy behalf. Thou couldst not keep the law; He kept it for thee. Thou couldst not obey God perfectly-lo! His obedience standeth in the stead of thy obedience-by it, thou art saved…Believe on Him, then, who on yonder tree with nailed hands and feet pours out His life for sinners. There is the object of thy faith for justification; not in thyself, nor in anything which the Holy Spirit has done in thee, or anything He has promised to do for thee; but thou art to look to Christ and to Christ alone. Then let thy faith behold Christ as rising from the dead. See Him-He has borne the curse, and now He receives the justification. He dies to pay the debt; He rises that He may nail the handwriting of that discharged debt to the cross. See Him ascending up on high, and behold Him this day pleading before the Father’s throne. He is there pleading for His people, offering up today His authoritative petition for all that come to God by Him. And He, as God, as man, as living, as dying, as rising, and as reigning above,-He, and He alone, is to be the object of thy faith for the pardon of sin.~ C.H. Spurgeon
